Correlation of Subjective Expectation and P300 Amplitude during a Game of Matching Pennies

Flexer A., Makeig S.

We report a study on two-person game playing involving simultaneous
EEG recording from both subjects. Independent Component Analysis is
used for identifying activities of individual cortical EEG sources.
Activity of a midline fronto-central component identified in four
of five subjects was correlated with a measure of subjective
expectation. This component accounts for the P300 waveform whose
amplitude varies depending on the context of the gaming situation.
